Jovian signal is observed at 20.1 MHz in the observatory installed at Darjeeling. As Jovian signal is studied under light of Jupiter-Io coupling, it is found that rainfall, out of different atmospheric components, has highest potential to influence reception of Jovian non-Io emission. The observations show that rainfall density plays crucial role in screening extra-terrestrial signal reception from Earth based observatories. The primitive study also suggests that cumulonimbus cloud may have effect on radio signal reception at high altitude. Some interesting findings regarding climatic influence on Jovian signal reception are reported in this paper.</span>
